Lawrence Weiskrantz FRS (28 March 1926 – 27 January 2018) was a British psychologist, who discovered the phenomenon of blindsight. Blindsight is when a person with a brain injury causing blindness can nevertheless detect, point accurately at, and discriminate visually presented objects.[1]

Early life[edit]

Weiskrantz originally attended Girard College, a boarding school in Philadelphia, due in part to the death of his father when he was six.[2] After graduating, he attended Swarthmore College and served in World War II.[2] Shortly before his graduation, he was awarded a Catherwood fellowship at Oxford University.[2]


Weiskrantz became Professor of Psychology at Oxford University where he remained a full professor until retirement in 1993.[2] He then became an emeritus professor of the university and an emeritus fellow of Magdalen College.[2] Weiskrantz had a lifelong interest in the writings and research of the Russian neuropsychologist Alexander Luria, whom he had met and befriended while Luria was still doing research.[3] The two remained colleagues until Luria's death in 1977.[3] Weiskrantz is generally credited with having discovered the phenomenon of blindsight following his book on this subject in 1986, which is the voluntary visually evoked response to a stimulus presented within a scotoma.[3]

Academic and service positions he held included:

  • Part-time Lecturer, Tufts University, 1952
  • Research Associate, Inst. of Living, 1952–55
  • Senior Postdoctoral Fellow, US National Research Council, 1955–56
  • Research Associate, University of Cambridge, 1956–61
  • Assistant Director of Research, Cambridge, 1961–66
  • Reader in Physiological Psychology, Cambridge Univ., 1966–67.
  • Founding President of the European Brain and Behaviour Society, 1969
  • Professor of Psychology, Oxford University, and Fellow, Magdalen College, Oxford, 1967–1993;
  • Professor Emeritus, Oxford University, 1993–2018 and Emeritus Fellow, Magdalen College, Oxford, 1993–2018.
  • Honorary President of European Society for Philosophy and Psychology.
  • Inaugural President of European Brain and Behaviour Society.
  • President of Association for Scientific Study of Consciousness.

Weiskrantz supervised at least 10 PhDs, including Alan Cowey, Charles Gross, Nicholas Humphrey, Susan Iversen, and Melvyn A. Goodale.


Weiskrantz was elected a Fellow of the Royal Society in 1980.[4] He was on its council in 1988–1989.[2] He was a member of the U.S. National Academy of Sciences, and of Academia Europaea.[2] Weiskrantz served on the Council of the Fyssen Foundation.[2]

Weiskrantz was a medalist of the Royal Society of Medicine and a medalist of the American Association for Advancement of Science.[2] He delivered the Heisenberg Lecture of the Bavarian Academy of Sciences/Siemens Foundation and the Ferrier Lecture of the Royal Society.[2]
